The drug-shaped stent is a spring-shaped device, covered with anti-inflammatory drugs and immunosuppressants that are used to unlock the arteries of the heart, brain or even kidneys.
They differ from conventional stents in that they contain drugs in their structures, these drugs are released during the first 12 months of implantation, in order to reduce the risk of cup closure In conventional models, which have only the metal structure, without drugs, there is an increased risk that, in the first 12 months of implantation , the glass closes.
- In angioplasty with a drug elution stent.
- The stent is inserted into the artery blocked by a catheter and acts as a frame.
- Which pushes the fat plaques that clog the artery.
- Preventing blood from passing.
- And?The walls of the artery so that it remains open.
- Allowing for better blood circulation.
- These stents also work by slowly releasing immunosuppressive drugs that reduce the risk of a new vessel closing.
The drug stent is indicated to clear the arteries, as long as they are not too tortuous or too close to a bifurcation, where 1 artery divides into 2.
For their high cost, drug elution stents are reserved for cases of patients at high risk of having a new cup closure, such as diabetic patients, extensive lesions, need to place many stents, among others.
The price of the drug stent is about 12,000 reais, but in some cities in Brazil it can be paid by the SUS.
One of the advantages of drug eluding stenosis over the use of traditional (metal) stenosis is the release of medication to reduce the risk of further stenosis or vessel closure.
